Belt-Driven Live Roller Conveyor Systems
Overview
Belt-Driven Live Roller (BDLR) conveyor systems are powered roller conveyors used for controlled transportation and accumulation of cases and totes. Power is transmitted from a centralized drive to individual rollers using continuous flat or V-belts, providing smooth product flow, predictable accumulation behavior, and low operational noise.
These conveyors are commonly applied in unit-handling systems where product control, modular expansion, and integration with automated equipment are required, including accumulation zones, merges, transfers, and curves.

Frequently Asked Questions
What products are best suited for belt-driven live roller conveyors?
Uniform cases and totes with stable bottom surfaces.
How is accumulation achieved?
Through photoeye-based zone control or adjustable pressure mechanisms.
Can curves and spurs be included?
Yes. Straight, curved, spur, and spur-with-curve configurations are available.
How are widths specified?
Widths are specified as nominal overall width, with between-frame width calculated accordingly.
Are accessories required for every application?
Accessories are application-dependent and selected during system engineering.
